there seems to be something blocking port 25 traffic to your server.
I can't reach any of them neither.
But they do reply on ping and on other protocols like pop3:
[karl@centos tmp]$ ping newgainde.qanet.gm
PING newgainde.qanet.gm (196.46.232.17) 56(84) bytes of data.

64 bytes from newgainde.qanet.gm (196.46.232.17): icmp_seq=2 ttl=54 time=120 ms
[karl@centos tmp]$ nc newgainde.qanet.gm 110
+OK Hello there.
quit
+OK Better luck next time.
however, no reply on smtp connects:
[karl@centos tmp]$ nc newgainde.qanet.gm 25
<nothing>
I guess you'll have to ask your ISP.
server6 : nc newgainde.qanet.gm 25

Bit slow. 29 sec portal to portal, and more typical QT and DT are sub
one second to around 6 seconds. (Second entry is a cross-box IMAP 'Sent'
folder router/transport).
OTOH... while Gambia is not the closest of destinations from Hong Kong,
and this server had no reason to have any route info cached...
.. neither did it reach him at the same IP as either of the two he's
having the problems with.
Dunno if that's an alias - or different boxen.
More digging needed, Kebba.
